The Observatory is a private teaching and research establishment, not a tourist attraction; it is not open to visitors, except as summarised below.
The Observatory holds free public open evenings, normally fortnightly on Fridays during UCL's autumn and winter terms (October–March inclusive), 18:30–19:40 and 19:45–20:55. The earlier tour may be preferable for families with children, but note that the content and nature of the tours (including negotiating some steep, open-tread stairs) mean they may not suitable for all children younger than 7–8 years old. (A single Saturday-evening tour is usually also offered each term for visitors unable to attend on Fridays for, e.g., religious reasons; these visits start at 19:00.)
Visitors are given a short introductory lecture followed by a full tour of the telescopes and facilities. During the tour season, only about 1 evening in 3 or 4 is clear, and in any event it may that neither the Moon nor the brighter planets are well placed for viewing. Nonetheless if weather permits, visitors will normally be given the opportunity to view the sky through the Fry 8-inch refractor.
N.B. – unfortunately, the site is not wheelchair-friendly, with gravelled grounds and steep stairways; disabled visitors should contact us in advance to enquire about access. There is no on-site visitor parking (other than by advance arrangement for disabled visitors).
Advance booking is essential; tours are very popular, and places are allocated on a first-come, first-served basis. A calendar of tour availability is given below; note that we have a strict limit on numbers, so even if there are "places available", this may mean only a single space.
Bookings requests should be made through the Observatory administrator, Mrs Kay Nakum, on 02031 081613, or by email to
For school visits please see our Outreach information.
We will consider requests for private group visits, subject to scheduling constraints. The itinerary will be similar to that for regular public tours (and is subject to the same caveats concerning weather conditions). Daytime visitors may be able to view the Sun using our specialised equipment. Charges are levied to cover staffing costs: 1-12 persons, £120; 13-24, £180; 25-36, £240. We regret that groups larger than 36 cannot normally be accommodated.
